It depends heavily on your current stack and functionality. In general, you can make an export of one of your subsites (including the plugins, themes, etc) and import that in a Version.

Deploy a Snapshot and create a new tenant based on that Snapshot. This allows you to test your product in WPCS without having to incur downtime. You can read more about this in our documentation.

After you have verified that everything is functional and in working order, contact us to discuss a migration plan. We are happy to help you migrate to WPCS.

Yes, you can place a CNAME record in your domain registrar. This way, when customers sign up on your website you can provide them with a subdomain (example.com, subsite1.example.com, subsite2.example.com) 

When customers are ready to launch their site, they can easily do so by changing their domain name. You simply have to add the main domain to the Tenant, Press verify and set it as the main domain. This can also be done using automations. We explain this in detail in our course.

Absolutely, we don’t have vendor lock-in. If one of your customers wants to leave, you can easily create an export of the website using the WP All in One Migration tool. If you want to leave, we will provide you with exports of your full stack at WPCS asap.

We are also working on the ability to download snapshots and tenant backups. This will allow you to host all the sites you have on WPCS on any traditional hosting solution.

We haven’t seen any plugins that are technically not supported so far. That being said, we do require plugins to ‘play nice’ with WordPress’ best practices. Especially when it comes to file management. Concretely: any plugin writing files must use the appropriate wp-content folder. (The path is found under the WP_CONTENT_DIR constant) 

We enforce this rule as both a security measure and as a best practice to keep your development cycle orderly and sane. From there, however, plugins are free to write to disk as they wish. As for adding constants to the wp-config.php file, this is currently not possible. 

We are working on allowing for tenant-specific constants to be defined before WordPress initialises. Until then, constants can only be defined in plugins or themes. If you have a specific case you’d like to discuss in this context, please let us know

It depends on what the SaaS/WaaS does. The most we can say is it won’t take much longer than if you’d build in WordPress elsewhere. We presume you also want to automate your business, which in total can amount to about a week. We include a full course after signing up for a trial.
